Can you help me with number 3 plz

Step-by-step explanation:

-x² + 6x - 9 = -(x² − 6x + 9)

= -(x - 3)²

then

the vertex is (3 , 0)

and the parabola is oriented down due to the minus sign at the beginning of the quadratic equation.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
